When the battery is charging, the CHARGE LED will be illuminated RED. The CHARGE LED will remain a solid RED color (not blinking) until the battery is fully charged.

When the battery is fully charged, the CHARGE LED will be illuminated GREEN. The CHARGE LED will remain a solid GREEN color (not blinking) until either the battery charger is disconnected or the battery becomes discharged.

If a Reverse Polarity condition exists, the ORANGE ERROR LED will illuminate. This ERROR condition will be displayed whether the charger is plugged in or disconnected from an AC power source. Reverse the battery connections to fix this ERROR.

If an ERROR condition exists, the Charge LED(s) will flash, and/or the ERROR LED with illuminate and/or flash. There are several reasons an ERROR condition could exist. For help troubleshootingERROR conditions, see the section entitled TROUBLESHOOTING.
